Listener Question Mini-Series: Hormone Cycles

Hi friends! We have one last episode left of our summer - listener question series where I have been answering questions that you sent in for me to discuss here on the podcast. I’ve really enjoyed this series and hearing the questions that you guys have and the topics that you want to talk about. Today’s question is about hormones, which oddly enough is a topic that I really enjoy talking about! So let’s dive in!

This listener asked a very intriguing question. She said she had seen a post talking about men’s hormones being compared to the sun’s cycle and women’s hormones being compared to the moon’s and was wondering if there was any truth to that. 

So here’s the deal. Women’s hormones and our hormone cycle are discussed a lot, but many people don’t realize that men also have a hormone cycle. They also don’t realize that men have the same main sex hormones as women - estrogen, progesterone, and testosterone - in very different amounts. 

So let’s talk about the male hormone cycle for a minute. Unlike women, men’s hormones operate on a 24-hour cycle and their primary sex hormone is testosterone. Generally speaking, a man’s testosterone levels peak in the morning, shortly after waking, and then gradually decline throughout the day, with their lowest levels occurring in the evening. Then their cycle starts all over the next day. However, in men, testosterone levels can be affected by their environment and emotions as well, so there can be fluctuations in levels during the day due to external circumstances. 

Women’s hormone cycles are quite a bit more complex. Generally speaking, women’s hormones operate on a 28-day cycle (although we know that number can fluctuate quite a bit) and estrogen and progesterone are the star players. Our cycles are broken down into 3 main phases: 

• The follicular phase begins on cycle day 1, or the first day of our period. During this phase, estrogen levels are rising and typically peak around cycle days 10-17. Testosterone levels also typically rise within this time leading up to ovulation. 

• Ovulation is the second phase of our cycle and only lasts for 1 day or a 24-hour period.

• After ovulation comes to the third phase which is called the luteal phase. During this phase, progesterone starts to peak and there is another rise in estrogen. If fertilization doesn’t occur, then all hormone levels decrease to their lowest points which triggers menstruation, and the cycle starts all over again. 

So in this way, the analogy used in this question is decently accurate. Men’s hormone cycles are often compared to the sun’s 24-hour cycle and a women’s is often compared to the 28-day cycle of moon phases.
